HYDRO'GARB ON BURNER.

Application filed January 16, I824. SeriM No. 686,600.

To all whom it may concern:

Be it known that I, Josnrn; C. Fnnenson, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Hydrocarbon Burners, of which the following is a specification.

This invention relates to certain improvements in hydrocarbon-burners and it is an object of the invention to provide a novel and improved device of this general character adapted for use in connection with furna'ces,iboilers and the like.

It is also an object of the invention to provide a novel and improved device of this general character wherein the liquid fuel is vaporized togetherwithmeans for spreading ordistributing the flame ina manner to obtain maximum heating efficiency.

An additional object of the invention is to provide anovel and improved device of this general character wherein the liquid fuel is converted into gasbefore being discharged from the burner and wherein is employed a regulatable fuel supply means.

The invention consists in the details of construction and in the combination and arrangement of the severalpartsof myimproved hydrocarbon-burner whereby certain important advantagesare attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel featuresof invention --will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the ac companying drawings, wherein I Figure 1 is a view partly in section and partly in :elevation illustrating a. burner constructed in accordance with an embodiment of my invention and in applied position, the adjacent portions of a furnace being diagrammatically indicated by broken lines;

FigureQ isa view in top plan of the burner as herein disclosed, the pipe lines associated therewith being omitted;

' Figure 3 is a-sectional view taken substantially on the line 33 of Figure l, with certain of theparts in elevation;

Figure a is a view partly in elevation and partly in sectioin of the device herein disclosed in applied position, certain of the parts of the furnace being indicated by broken lines, the device being arranged at substantially a quarter turn with respectto the illustration in Figure 1.

My improved burner is adapted to be positioned within the fire box of a furnace or the like and comprises a base B which is positioned directly upon and supported by the grate G diagrammatically indicated by broken lines in Figures 1 and 4. l

The base B has its central portion raised, as at 1, to provide a chamber2 open atfits lower end. The side wall of the chamber 2 at a predetermined point above its lower open endis provided with an annular shoul der 3 providing an abutment for a plate 4 intersecting the chamber 2 in a horizontal direction. The plate 4 may be held in applied position in any desired manner but as herein disclosed the holding screws 5 are employed.

The central portion 6 of the plate 4 is imperforate and said imperforateuportion is substantially defined by an upstanding continuous flange 7resulting in the formation ofa cup to receive liquid fuel which maybedr'opped from the burner [proper the event the flame shouldbe extinguished. Leading from the :cup 7 is a pipes which preferably extends exteriorly from the furnace or the like through the ash ,p'it as ijs illustrated in Figure '1 of the accompanying drawings. This pipe 8 .is preferably intended to lead toa mechanism forl-automatically shutting off the feed 'va lveifor the burnerproper under suchcontlitions. How ever, as this mechanism forms no part of the present invention an illustration or jdeseription thereof is believed unnecessary.

The top wall 9 of the base :B is provided with a relatively large central opening 1.0 defined by an upstandingcontinuous flange is provided, the air circulation being up- Wardly from the ash pit of thefurnace or the like, through the openings i191 "in the portions of the plate 4; outwardly of the imperforate portion '6 and especiallythrough the flue 10, as is mama-teeny thearrows in Figures 3 and 4;. a g 1 Leading from a suitable source of fuel supply is a pipe-linefL, This line Lextenlds within the ash pit of the furnace or the'like and is then continued upwardly through the 11 of desired length whereby ;a drafll flue grate G and through a suitable opening 1 1 provided in a marginal portion of the base B. The end portion of the line L within the furnace and above the grate Gr is coupled, as at 15, to a horizontally disposed coil 16. The coil being herein disclosed as comprising substantially a single convolution and which has its bore of a diameter considerably in excess of the diameter of the line L or more particularly that portion of the line immediately adjacent to the coil.

The end portion of the coil 16 remote from th coupling 15, is coupled, as at 17, to an upstanding pipe 18 having its bore of a diameter substantially the same as the diameter of the bore of the coil 16. The upper portion of the pipe 18 is coupled, as at 19, with an inwardly disposed pipe 20 which has its inner end portioncoupled, as at "21, to a depending pipe 22. The bore of the pipe20 is materially less than that of the pipe 18 and as herein disclosed, the bore of the pipe 22 is of a diameter greater than that of the pipe'18. By reducing the bore of the pipe 20 the vaporized fuel or gas is caused to enter and pass through the pipe 22 with increased force whereby the efi iciency of the device is materially increased.

The lower end portion of th pipe 22 is coupled or connected, as at 23, with the upper portion of a hollow burner member 24, said member 24: being herein disclosed as substantiallyin the form, in crosssection, ofa triangle with its apex downwardly disposed and positioned at substantially the axial center of the opening 10. The walls of the member 24 at the upper portion thereof are provided with the jet openings 25 where the vapor or gas is ignited. These openings 25, as is clearly illustrated in Figures 3 and 4: are arranged'within the-'field defined by the'coil 16 so thatthe flame or blaze will effectively heat the coil 16 to convert the liquid fuel into the desired gas or vapor. The upperportion of the burner member 24 is defined by the upwardly disposed and abruptly flared spreader flange 26 whichopcrates further to assure theproper action of the flame or blaze upon the coil 16 and also to distribute the flame or blaze within the firebox of the furnace to assure a maximum of heating efiiciency and more particularly when the burner is employed in connection with a hot water or steam heating system although I do not wish to be understood as limiting myself to any particular use of my improved burner.

I In order to increase the strength of th assembled device and to maintain the same effectively in assembled relation the flange 26 is connected at desired points with the upper wall 9 of the base B by the bolts 27, each of said bolts being surrounded by a spacer sleeve 28 interposed between the wall 9 of the base 13 and the flange 26. Each of the bolts 27, as herein disclosed, also has interposed between the upper surface of the flange 26 and the holding nut 29 a spacer sleeve 80.

Arranged within the line L at a point exterior of the furnace or the like is a needle valve 31 serving to regulate the flow of the liquid fuel from the source of supply to the coil 16 and in practice, I find it of special advantage to adjust the valve 31 in a manner whereby the liquid fuel will pass the valve in drops as I have fully demonstrated in actual practice that the feed of this kind results in the burner operating to the best advantage and in a manner whereby the waste of fuel is substantially eliminated.

In practice, the flame or blaze from the jet openings 25 is further distributed within the fire box through the medium of the draft passing through the flue 10, such draft, also supporting combustion ina manner whereby smoking and the like is avoided.

When the assembled device is applied within the fire box of a furnace or the like the portions of the grate outwardly of the raised portion 1 of the base B and the side walls of the furnace are closed or sealed, as at 32, preferably by asbestos cement.

The coil 16 maybe initially heated in any manner preferred but as herein disclosed the flue 11 is surrounded by a gas burner 33 in communication through the pipe 34 with a suitable source of gas supply, said pip 3 1 being disposed through a suitable opening 35 produced in the peripheral portion of the base 13 and extending exteriorly of the furnace or the like through the ash-pit, as is clearly indicatedin Figure 1 of the accom- 'panying drawings.

From the foregoing description it is thought to be obvious that a hydrocarbonburner constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
